If the business rule for processing charges that belong to the miscellaneous charge category involves booking them as an unplanned cost in the downstream ERP system, then this is configured using the Always Booked To Unplanned setting.

For example, the following table contains the values for the columns in the Settings > Invoice Processing > Capture Profiles > Misc Charge Settings > Misc Charge Categories tab.

During export, the total value of all miscellaneous charges in every category that requires unplanned delivery cost handling are passed to an export database field into the "Postage" field as configured in the Settings > Invoice Processing > Invoice Export > DB Export Settings > DB Export Settings - Header Table tab.
